IHydroxyethylcellulose (HEC) yipolymer enyibilikayo emanzini esetyenziswa kakhulu kumashishini ahlukeneyo kubandakanya ukwakhiwa, ukutya, amayeza kunye neemveliso zokhathalelo lomntu. Yinto yendalo, i-biodegradable material ephuma kwi-cellulose, i-carbohydrate efumaneka kwiindonga zeeseli zesityalo. Kwiingubo zendalo zamatye, i-HEC idlala indima ebalulekileyo ekuphuculeni ukusebenza kunye neempawu zobuhle zokugqoka.
Iingubo zamatye zendalo zisetyenziselwa ukukhusela kunye nokuphucula ukubonakala kwamatye endalo njengemarble, granite kunye ne-limestone. Ezi zogquma zinika umaleko wokukhusela kwimozulu, ukubola, ukubola kunye nokukrwela. Bangakwazi nokuphucula umbala, ukukhanya kunye nokuthungwa kwelitye, ngaloo ndlela kuphuculwe ubuhle bayo bendalo.
Nangona kunjalo, iingubo zamatye zendalo zijongene nemingeni emininzi ngokusetyenziswa, ukubambelela kunye nokusebenza. Ingubo kufuneka ibambelele ngokuqinileyo kwindawo yamatye ngaphandle kokulimaza ilitye okanye ukuphazamisa ukuthungwa kwayo kwendalo. Kufuneka kwakhona zixhathise kwimitha ye-UV kunye nolunye uxinzelelo lwendalo olunokubangela ukuthotywa okanye ukujika kombala ngokuhamba kwexesha. Ukongezelela, ipeyinti kufuneka ibe lula ukuyisebenzisa, yome ngokukhawuleza, kwaye ingabikho ukukrazula okanye ukukhupha.
Ukujongana nale mingeni, iingubo zamatye zendalo zihlala zibandakanya izongezo ezahlukahlukeneyo kunye nezizaliso zokuphucula iimpawu zabo. I-HEC yenye yezongezo ezisetyenziswa ngokuqhelekileyo kwezi zogquma ngenxa yeempawu zayo ezizodwa.
Indima ephambili ye-HEC kwiingubo zendalo zamatye kukusebenza njenge-thickener, i-binder kunye ne-rheology modifier. Iimolekyuli ze-HEC zinemigca emide yemigca efunxa amanzi kwaye yenze into efana nejeli. Le nto ifana nejeli ijiya iifomyula zepeyinti, izenze zibonakale ngakumbi kwaye kulula ukuzisebenzisa. Ukongezelela, i-gel-efana ne-gel inokubonelela ngokuzinza kunye nokusabalalisa okufanayo kwamacandelo okugubungela, ukuthintela ukuhlalisa okanye ukuhlukana.
I-HEC isebenza njenge-binder ukuphucula ukunamathela kwengubo kwindawo yamatye. Iimolekyuli ze-HEC zinokudibanisa kunye nemigangatho yamatye kunye nezixhobo zokugquma ukwenza iibhondi eziqinileyo nezihlala ixesha elide. Le bhondi iyamelana nokucheba, i-spalling okanye i-delamination phantsi koxinzelelo, iqinisekisa ukubambelela kwexesha elide kunye nokukhuselwa kwendawo yamatye.
I-HEC iphinda isebenze njenge-rheology modifier, ilawula ukuhamba kunye ne-viscosity yengubo. Ngokulungelelanisa ubungakanani kunye nohlobo lwe-HEC, i-viscosity kunye ne-thixotropy yengubo inokulungelelaniswa ukuze ihambelane nendlela yesicelo kunye nokusebenza okufunayo. Thixotropy yipropathi yepeyinti ehamba ngokulula xa iphantsi koxinzelelo lwe-shear, njengokuba ngexesha lokuxuba okanye ukusetyenziswa, kodwa iyancipha ngokukhawuleza xa i-shear stress isusiwe. Le propati iphakamisa ukusasazeka kunye nokugubungela i-coating ngelixa inciphisa ukuvuza okanye ukugoba.
Ukongeza kwindima yayo yokusebenza, i-HEC inokuphucula iimpawu zobuhle beengubo zendalo zamatye. I-HEC inokunyusa umbala, i-luster kunye nokuthungwa kwengubo ngokwenza ifilimu egudileyo kunye neyunifomu kwindawo yamatye. Ifilimu ikwabonelela ngenqanaba lamanzi kunye nokumelana namabala, ukuthintela amanzi okanye olunye ulwelo ukuba lungaguquguquki okanye lungene kumphezulu wamatye.
I-HEC ikwayimathiriyeli yendalo kunye nokusingqongileyo ekhuselekileyo ekusetyenzisweni nasekuyilahleni. I-biodegradable kwaye ayivelisi nayiphi na imveliso eyingozi okanye izinto ezikhutshwayo ngexesha lemveliso okanye ukusetyenziswa.
Isishwankathelo, i-hydroxyethyl cellulose (HEC) idlala indima ebalulekileyo ngokuphucula ukusebenza kunye nobuhle beengubo zendalo zamatye. I-HEC isebenza njenge-thickener, i-binder kunye ne-rheology modifier, iphucula i-viscosity, i-adhesion kunye nokuhamba kweengubo. I-HEC inokuphucula umbala, i-gloss kunye nokuthungwa kweengubo kunye nokubonelela ngeqondo lamanzi kunye nokumelana nebala. Ukongeza, i-HEC yinto yendalo, i-biodegradable imathiriyeli ekhuselekileyo kwaye inobuhlobo nokusingqongileyo.
